Letters Patent No. 108,772, dated November 1, 1870.

IMPROVEMENT IN BLlNG-PRESSES.

The Schedule referred to in these Lettersv Patent and making part of the same. A

To all whom it may concern.-

. Be it known that I, GEORGE DUNCAN, of San Francisco, in the-county of San Francisco and State of Californiafhave invented certain new andV useful Improvements in Ealing-Presses; and Ido hereby declare that the following-is a full and exact description of the same, reference being: had to the accompanying drawing and to the letters of reference marked thereon.

-My invention relates to certain improvements in that class of baling-presses that have. the top side hinged in such a manner as to open and receive the material to be compressed, and in which the follower moves in a horizontal direction, the object of which is to provide -a greater 'cramping-surface and a more simple and reliable baling-machine than those hereto-y fore used;

This invention consists. of an improved lever arrangement for working the follower, and an improved device for working the cover, the-details of the construction and operation of which are more fully described hereinafter.

In the drawing- Figure 1 is a longitudinal vertical section of a balf ing-press having my improvements.

`Figure 2 is a plan of the-same, w'- h certain parts removed. U

Like letters refer to like parts in all of thefigures.

Ais the'space in which the bale is compressed, and is inclosed at the top by the cover B, hinged at C, and is contracted or enlarged by the movements of the follower D.

The follower D is moved by means of the lever E, and is guided in a right line by the easing or frame F and the guide-rod'G.

The guide-rod G is attached to the follower and slides through suitable mortises.

One extremity of the lever E is hinged to thefollower at H. v

The other extremity lto which the power is'applied is provided with a roller lor* wheel, I, that may run, when the machine is inoperation, upon the floor or other horizontal plane surface prepared for it, t0 avoid friction on the framework between which the lever operates.

A fulcrum is provided for lever E by means of the pin J, having friction-rollers KA working between the transverse guides L.

In the drawing the lever E is in a longitudinal postion with reference to the press.

The follower D is at that extremity of its stroke at which the space A is the most contracted, and a stop, M, is provided to prevent the lever E from being moved in that direction; but the lever maybe moved around through an angle of ninety degrees until Ait becomes parallel with the guides L, and the pin J lower will be drawn back toward the guides L, en I larging the space A.

When the press is to be filled the lever E is drawn into this last-mentioned position and the cover B raised Vby means of the rope N and windlass O, and a proper quantity of the material to be baled -is placed in the space A. The cover B is then allowed to descend until it rests upon the top of the material, and is then brought down to the position shown iu the drawihg by means of the purchase-plate R, link S, and handbar T.. 1

The purchase-plate R is provided with sockets, U,

shownin dotted lines inthe drawing, for receiving the bar T. v

The purchase-plate B being hinged tothe frame E, as shown, and the link S being hinged to that plate, as shown, and catching or working ,in the hook V, the pressure on the under side of the cover` B, however great, can never change the position of those parts fromthatshown in the drawing, and to release the hook V from the link S, the purchase-plate must be turned on its hinge by means of the hand-bar, causing the lower end of thelink to cross the line of the hook and hinge, and continue turning until the link is raised sufficiently high to allow of its being released froi the hook. i

W are grooves or recesses for 7the bale-ropes.

4After the space A has been illed and the cover B brought down to the position shown in the drawing, the follower may be forced in .to compressthe bale, and the bale then bound in the usual manner and re# moved through the doorway X.

It is evident that in either b l'ngiug down the cover A or in forcing in the follower, a uniform and constant power applied to move the ends of either the hand-bar lor the lever E, will steadily overcome the. coustantlyfincreasing resistance of the material in the space A undergoingl compression.

The position and arrangement of the parts giving a large horizontal opening throughwhich the space .A can be filled, evidently offers greater facility in baling than would either a smaller opening or a vertical opening of the same size.

Havingthus described myinvention,

What I claim, and desire to secure by Letters Pat# eut,isv

1. rlhe purchaseplate It, worked by a hand-bar, T, hinged as described, and provided with a link, S,

working in a hook, yV, arrangedand operating snbstantially as described,'to overcome the pressure on the inside of, and to securely close or release, the door B.

2. The lever E, hinged to the follower '1), and prof vided with n movable fulcrum by means of pin J, friction-roller K, AWorking in guides L, all constructed and arranged as shown, and for the purpose setforth.

3. The combination, in a. bnling-press,of'the follower D when operated by the lever E, with the cover B when operated by the rope N, windlass O, l'nnrchase-plate R, and link 8,311 constructed and errangell as described, and for the purpose set forth.

In witness whereof, I have hereunto set my hand and seal.

GEORGE DUNCAN. [14. s.]
